Major root file system crashes after messing with virt-manager/virsh edit












0















I have had two recent incidents of major root filesystem corruption after modifying or attempting to modify virtual machine domain XML file. In the first case, I don't remember if I actually succeeded in modifying the domain XML, but when I started the VM, virt-manager froze, I was unable to restart, so I did a hard reset. On restart, I got a GRUB rescue screen. Inspecting with gparted showed that my RAID1 array (my root FS) still existed, but the partition tables on it were gone.



I assumed that this was a one-off freak thing, possibly related to overused SSDs, so I tried again with a pair of brand new SSDs (in RAID1, which was also the case on the first go-round). This time, I again succeeded in creating a VM, but when I tried to use virsh-edit, I got a file system not writeable error. After restarting (I have a RX470 card which forces me to restart the machine between VM reboots), I got fcsk problems:
enter image description here



I don't know if the two are related, but they both seem to have to do with corruption and happened after monkeying with KVM/virt-manager. I don't know where to go from here. Is this a bug in something virtualization related that corrupts my disks? Is something about my system configuration or partition scheme making me vulnerable?



I realize that the fact that two different types of crashes does not bode well for reproducibility or troubleshooting, but I any suggests/stories about similar situations would be helpful.
